In Hegel there are three elements, Spinoza's Substance, Fichte's Self-Consciousness and Hegel's necessarily antagonistic unity of the two, the Absolu… - Benedictus de Spinoza

In February of 1927, the historian Joseph Klausner stood before an audience at Hebrew University in Jerusalem and delivered a lecture on the “Jewish character” of Baruch Spinoza's philosophy. As he neared the end of his talk, Klausner dropped the usual academic idiom and, with great passion, announced his intention to bring Spinoza, excommunicated in 1656 by the Portuguese-Jewish community in Amsterdam, back into the Jewish fold. “To Spinoza the Jew,” he declared: “The ban is nullified! The sin of Judaism against you is removed and your offense against her atoned for. You are our brother! You are our brother! You are our brother!” Klausner's theatrical performance was the first of several efforts in the 20th century to revoke Spinoza's excommunication. No less an eminence than David Ben-Gurion, the first prime minister of Israel, publicly argued for “amending the injustice” done to the philosopher, insisting that the 17th-century rabbis had no authority “to exclude the immortal Spinoza from the community of Israel for all time.” All these efforts were unsuccessful (not to mention unauthorized). Unlike most of the bans issued by the Amsterdam Portuguese in that period, the ban on Spinoza was never rescinded. In fact, in 1957, Rabbi Solomon Rodrigues Pereira of Amsterdam even reaffirmed the excommunication. Like Galileo, disciplined by the Roman Catholic Church just two decades before him, Spinoza has gone down as one of history's great thinkers punished by intolerant ecclesiastic authorities for his intellectual boldness.

Jefferson instead recognizes that the multitude will act at times on the basis of ignorance, and yet he still affirms not only their right to rebel but also the benefits of their rebellion. His thinking in this regard runs parallel to that of Spinoza, and, in fact, Spinoza's thought can help carry this line of democratic thinking further. The two thinkers share a pair of basic assumptions: one on the virtue of disobedience, since freedom can never result from obedience to authority; and another on the capacities of the multitude, even though it is born ignorant, to become intelligent and rule itself autonomously. The process leading the multitude from ignorance to wisdom is indeed the steep path that runs throughout Spinoza's work.

I can always say to myself that my atheism, like that of Spinoza, is true piety towards the universe and denies only gods fashioned by men in their own image, to be servants of their human interests; and that even in this denial I am no rude iconoclast, but full of secret sympathy with the impulses of idolaters.
